TITLE:
PHP-Fusion Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA19992

VERIFY ADVISORY:
http://secunia.com/advisories/19992/

CRITICAL:
Moderately critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
PHP-Fusion 6.x
http://secunia.com/product/5291/

DESCRIPTION:
rgod has reported some vulnerabilities in PHP-Fusion, which can be
exploited by malicious users to compromise a vulnerable system.

1) The vulnerability is caused due to an error in the handling of
file uploads where a filename has multiple file extensions. This can
be exploited to execute arbitrary PHP code by uploading malicious
avatar images.

Successful exploitation may allow execution of script code depending
on the HTTP server configuration (it requires e.g. an Apache server
with the "mod_mime" module installed).

2) Input passed to the "settings[locale]" parameter in
"infusions/last_seen_users_panel/last_seen_users_panel.php" is not
properly verified before being used to include files. This can be
exploited to include arbitrary files from local resources.

Note: This is only vulnerable on windows systems.

The vulnerabilities have been reported in version 6.00.306. Other
versions may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly verified.

Grant only trusted users access to affected systems.

PROVIDED AND/OR DISCOVERED BY:
